Specification of Letters Patent.

Patented May 12, 1914.

Application filed July 3, 1911. Serial No. 636,638.

1 '0 all whom it may concern Be it known that we, Ran A. EDGERTON andSIMON DINovsKY, of Utica, in the county of Oneida and State of New York,have invented certain new and useful Improve ments in Machines forSharpening Tailors lVax; and we do hereby declare that the following isa full, clear, and exact description thereof, which will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to thereferencenumerals marked thereon, which form part of this specification.

Our present invention relates to an improved machine for sharpeningtailors wax.

Our object is to provide a machine that will have a device for holdingthe wax and bringing it into engagement with proper cutting memberswhereby the wax is safely conveniently and quickly sharpened.

A further object is to provide means whereby the wax after each strokeof the moving member will be fed into engagement with the guide-way sothat another shaving may be removed by the cutters at the next stroke.

Another object is to provide automatic means for releasing the hold ofthe support and the pressure of the feed device after each stroke sothat the wax may be removed from the machine without furth r movement bythe operator and the machine will be in position to receive anotherpiece of chalk.

A further object is to provide a feed pressure device that will adjustitself to pieces of wax of varying width. I

Fig. 4 is anend view of the sliding carriage and wax support. Fig. 5is aplan view ofanother form of a machine embodying our invention. Fig. 6 is a sideelevation of the same. Fig. 7 is a vertical cross sectional view on line7-7 of Fig. 6. Fig. 8 is an end view of the bracket and its attached waxsupport.

Referring to the drawings in a more particulardescription and referringfirst to the form of machine illustrated in Figs. l1, there is shown aplatform 10 preferably forming the top of a box 11 in Which may beplaced an open-topped drawer 12 into which the shavings of wax may fallthrough the central opening 13 in the platform 10. Above the latformopening 13 and supported by brldges 1d are placed two parallel andlongitudinally arranged guides 15 havmg their opposing faces slantingtoward each other at the bottom to form a V-shaped guide-way 16 toreceive the wax 18 and of substantially the angle of the wax whensharpened. Suitably mounted in each of these guides 15 and slightlyprojecting therefrom into the guide-way 16 are cutting members'17 of anydesired form and having their cutting edges so shaped and so placed withreference to each other as to shave the wax 18' t0 the desired angle.

Slidingly mounted upon the guides 15, 15, 1s a carriage 19 retained onsaid guides by overhanging sides 19 engaging the outer sides of theguides and by flanges 19 engaging the bottom of said guides but of suchprojecting length as not to come into contact with the bridges 14. Fromthe top of said carriage rises a longitudinally arranged upright 20having its end 20 toward the right as viewed in Figs. 1 and 2 extendeddownwardly in a V-shaped pointinto the guide-way 16 and forming acontact support for one end of the piece of wax 18 and adapted tosupport substantially that entire end of the wax as it is shoved towardthe right past the cutters 17 by a movement of the carriage 19.

Pivot-ally mounted upon the upright 20 at 21 is an arm 22 extending tothe right of the upright 20 to a point about midway of the piece of wax1S, and having at that end a V-shaped finger 23 overhanging the guideway16 and the wax 18 therein and adapted to press down upon the top of thewax under the tension of a spring 24 suitably mounted upon the upright20. The left hand end 22" of the arm 22 projects beyond the pivot 21 andthe upright 20 and, as the carriage is moved to the extreme left end ofthe guides 15, this end 22 comes into camming engagement with the underside of a fixed slanting arm 25 secured to the guides 15, and is therebydepressed causing the other end of the arm with its finger 23 to beraised from the wax as indicated in dotted lines in Fig. 2. Centrallyand horizontally pivoted upon the carriage 19 at 26 is another arm 27having one end 27 reaching past the wax and then turned in at rightangles across the guide-way 16 just beyond the farther end of the wax. Aspring 28 upon the carriage 19 is tensioned to keep the end 27 acrossthe guide-way. The object of this arm is to have the end 27 draw the waxback past the cutters 17 on the backward stroke of the carriage and tokeep it in close contact with the support 20 so that there will besubstantially no lost motion when the next forward stroke is taken. Inorder to release this holding arm from contact with the wax so that itmay be easily removed when sharpened, the end 27 is withdrawn fromposition across the guideway 16 at the end of each return. stroke by theother end 27 of the arm being brought into camming engagement with aprojection 29 at the left end of the guides 15 so that the arm 27 ismoved to the position indicated in dotted lines in Fig. 1. At the innerend of the camming edge 27 there is provided a recess 27 allowing theend 27 to spring out part way and engage the projection 29 and hold thecarriage in the extreme left position against the tension of bothsprings 24: and 28. In this position it will be obvious that the finger23 and the end 27 pf arm 27 are out of engagement with the wax so thatthe wax already sharpened may be removed without further movement of themachine by the operator and a new piece may be inserted preparatory tosharpening. It will be understood that after each sharpening and in factafter each return stroke the machine will be brought to this lockedposition.

Assuming that the wax to be sharpened has been inserted in the guidewayclose to the support 2O the operation of the machine will be as follows:The initial forward movement of the carriage by means of the operatormanually operating the handle 30 at the top of the upright 20, willcause the projection 2) to ride over the rearward sloping side of thelocking recess 27. As the carriage is farther advanced toward the rightthe arm 22 will be released from its camming engagement with arm 25 andunder the tension of spring 24 the finger 23 will press the wax 1Sfirmly down into the guideway 16. At the same time the arm 27 will havebeen released from engagement with projection 29 and under the influenceof spring 2 1 the end 27 will have passed around the forward or rightend of the wax, steadying the wax during forward movement of thecarriage and in position to draw back the wax with the carriage upon thereturn stroke. A further forward movement of the carriage carries thewax past the cutting members 17 which preferably being several in numberon each side of the wax will take off several thin shavings therefrom. Astop 31 upon the guide 15 arrests the forward movement of the carriageafter the entire wax has been moved past the cutting members. Upon thebackward stroke the wax is carried back past the cutting members bymeans of the end 27 of arm 27 and at the end of the return movement thefinger 23 and arm 27 are locked out of engagement with the wax.Successive forward and backward strokes are made until by the feed ofthe wax by the spring pressed finger 23 and successive shaving of thewax by the cutters, the desired edge is produced upon the wax.

It will be understood that the shavings of wax will be saved to meltover into new forms and that this saving will be encouraged. byproviding a machine which will so quickly and effectively sharpen thewax without danger of the person cutting his fingers.

Within the drawer 12, may be mounted a swinging partition 32 operated bya handle 33 projecting without the drawer. By means of this swingingpartition the shavings of wax may be kept separate from the shavings ofchalk sometimes used by tailors. It will be understood that theoperation of our machine would be the same with wax, chalk or any othersimilar material and that we have used the term wax as including anysuch material.

Referring now to the form of machine illustrated in Figs. 58, it will beseen that, instead of stationary guides holding the out ters againstwhich is carried the wax by a carriage slidingly mounted. on saidguides, the wax support is stationary and the guides and cutters aremoved past the wax. As the details of this construction and theprinciple of operation thereof are so near alike, a detailed descriptionof the parts is not deemed necessary except where they vary from thefirst described form.

Upon the cent-rally slotted platform 10 are provided metal tracks 3 1having upturned ends and 36 at right and left ends respectively viewedin Figs. 5and 6. Slidingly mounted on these rails 34L- by means of legs37 and rollers 40 are the guides 15 having the V-shaped guide-way 16,cutting members 17 and slanting arm 25 and projection 29 as heretoforedescribed. Fixed to the platform 10 is a bracket 38 projecting over theguide-way 16 and affording support for the upright 20 and its supportingfront edge 20 and to which bracket is pivotally secured the arm 27 andspring 28 as and for the purposes already described, while to thesupport 20 is pivoted the arm 22 with its operating spring 21 and forkedfinger 23 as already described. Fixed to the guides 15 is a handle 39 bywhich the operator will shove the cutter holding guides back and forthpast the fixed bracket 38 holding the wax. It will be obvious that themotion to the left will now be the cutting stroke and the motion to theright will bethe return stroke but it will be apparent that theresulting operation will be equivalent except that themachine will bebrought to locked position with arms 2% and 27 released at the end ofthe forward movement instead of at the end of the return movement. Thespring tensioned feed will be operative as before to feed the wax intothe guideway as needed. The upturned ends 35 and 36 of the track 3%serve as backward and forward stops limiting the movement of the slidingguides by contact with the rollers 40.

It will be noticed that the V-shaped guideway 16 is not closed at thebottom but open by reason of the guides 15 being slightly spaced apart,and this arrangement permits any shavings of the wax that get into theguideway to fall through the open bottom or be easily shovedtherethrough at either stroke instead of clogging up and breaking thewax. Ordinarily most of the shavings will fall from the cutting memberswithout lodging in the guideway which is cut away near the cuttingmembers for that purpose, as indicated in Figs. 3 and 7.
